Geep Chryst does not believe Colin Kaepernick regressed during the 2014 season.

In what became the final season of Jim Harbaugh's tenure as head coach, Kaepernick had a career high in passing yards and his completion percentage improved but he threw more interceptions, fewer touchdowns and also took 13 more sacks.

"Last year, you're playing with some different sets of challenges," Chryst said, via the San Jose Mercury News. "There was more change within the offensive line than he had experienced the last couple of years. How does that affect your production as a quarterback? You're behind more often in games. How does that affect your production as a quarterback? I cite the fact that we had six touchdowns nullified by penalty. You plug that back into his formula, he really wasn't ... he didn't regress off his line as much as perceived."
